I missed seeing names of any CAD vendors other than Autodesk in yesterday's article, but in a posting on slash.dot today I see that Siemens is also on the list.
(The law suit seeks the protect BetaNet's patent on adding activation-licensing data to downloaded software.)
Because the suit names "Siemens Corp," it targets Siemens USA, not Siemens AG (the head corporation located in Germany).
The complete list consist of:
International Business Machines
Sony Creative Software
